2019-06-09  Edward Smith-Rowland  <3dw4rd@verizon.net>

	Fix ConstexprIterator requirements tests - No constexpr algorithms!
	* testsuite/21_strings/basic_string_view/requirements/constexpr_iter.cc:
	Replace copy with hand-rolled loop.
	* testsuite/23_containers/array/requirements/constexpr_iter.cc:
	Ditto.
